if I'm not mistaken, those are connect from one manifold to the other with a decent sized hose. It helps the engine to drive and idel smoother by balancing the pressure pulses.

That makes perfect sense. It could balance the intake vacuum pressure

Perfectly correct, this stops the fuel from stop / starting in the manifold, giving a buffeting effect.

When the fuel flows then has to stop, and then start flowing again.

Makes balancing the carbs much easier as well .

Means your car runs smoother.
